The best foods for cats to gain weight include high-protein, low-fat meats, nutrient-rich cat food, and appropriate amounts of carbohydrates.
First, high-protein, low-fat meats such as salmon and chicken breast are ideal for weight gain. These meats are not only rich in protein but also easily digested and absorbed, helping cats gain weight while maintaining their health. For example, salmon, due to its high-protein, low-fat properties, not only aids in weight gain but also protects the cat's pancreatic and cardiovascular health; chicken breast, being hypoallergenic and easily digestible, can help cats gain weight and boost their immunity.

Secondly, choosing high-protein, easily digestible cat food is the best way to help your cat gain weight. We recommend products like "Miracle Cat Food," which contains up to 86% meat and 43% crude protein, providing ample nutrition to help your cat gain weight and develop fuller cheeks.
In addition, a moderate intake of carbohydrates can also help cats gain weight. Although cats are primarily carnivores, a moderate amount of carbohydrates, such as starches, can help provide energy and promote weight gain. However, excessive intake may lead to problems such as indigestion, so it should be controlled between 15% and 35% of their total food intake.
